Use linear approximation, i.e. the tangent line, to approximate v27.08 as follows. Let f(x) = x and find the equation of the tangent line to f(x) at x = 27 in the form y = ma + b. Note: The values of m and b are rational numbers which can be computed by hand. You need to enter expressions which give m and b exactly. You may not have a decimal point in the answers to either of these parts. m= b = Using these values, find the approximation. V27.08 ~ Note: You can enter decimals for the last part, but it will has to be entered to very high precision (correct for 6 places past the decimal point)
